84 brake seals

[PEIslander]

I'm planning to replace the brake caliper seals on my 84 Standard and when looking up the part numbers on Yamaha's website it shows "part # 31A-W0047-00-00 Quantity 2 " for the rear seal kit. I checked Flatout's and it shows the same thing.

 

Anyone know why it shows 2 sets for the rear caliper? but only 1 set for each front caliper.

 

Thanks

Man I can't believe I've forgotten, and I've rebuilt all the early mark I calipers. If I foggily remember correctly the rear caliper piston is larger than the fronts, and they sell the seals and 'O' ring seperately for each side/piston??? I guess the front 'kit' came with 2 of each so only takes one 'kit', and is priced that way. The rear seals have to be bought seperately as there isn't a 'kit' so you'd need to buy 2?? i think........
